Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a terminal block arranged in a connection terminal box of a telephone wire cable.

<Prior art> For example, in a connection terminal box for connecting a fictitious telephone line cable, usually, a required number of terminal blocks having four pairs of terminals are arranged, and a telephone line cable and a subscriber telephone are connected. Are making connections.

On the other hand, the telephone line cable is provided with a contact line for communication at the time of testing, and this contact line is also laid in the connection terminal box, and this connection line is a dedicated terminal block arranged in the connection terminal box. Connected to. Then, the operator of the telephone line construction connects the terminal of the terminal block for the communication line with a breast or the like and confirms the connection while communicating with the test stand of the station.

<Problems to be solved by the invention> Thus, in the conventional connection terminal box of the telephone line cable,
In addition to the terminal block for connecting the telephone line, the terminal block dedicated to the communication line was placed, so the space inside the box was narrowed, the weight was heavy, and the cost of connecting parts was high. Atsuta

<Means for Solving the Problems> The present invention has been made to solve the above problems, and by adding a contact terminal for a contact wire to a part of the terminal block, a terminal block dedicated to the contact wire is provided. Is unnecessary,
It is an object of the present invention to provide a low-cost terminal block for a connection terminal box.

For this purpose, the terminal block for the connection terminal box of the present invention is arranged in the connection terminal box of the telephone line cable, and the terminal projecting from the main body is covered with an insulating cap, and the cap is screwed to the main body. In the terminal block for the stopped connection terminal box, the connecting terminal is sandwiched and fixed between the cap and the main body.

In addition, if the connecting terminal is provided with a mounting hole at the center and the cap tightening screw is inserted into the mounting hole via an insulator, the connecting terminal can be more securely fixed. You can

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a front view of a terminal block for a connection terminal box, and FIG. 2 shows a plan view thereof. This terminal block has four pairs of telephone wire terminals and a pair of connecting terminals, and 1 is a synthetic resin main body, and two mounting screws 2 are embedded in the lower part in a state of protruding downward. Furthermore, four pairs of terminals 3 and 3 for telephone wires are provided on the inclined surfaces on both sides of the upper portion of the main body 1 (see FIG. 2,
(FIG. 3), a screw 4 for cap tightening is provided in the middle of the terminals 3, 3.

The terminal 3 provided so as to be implanted in the main body 1 has a structure in which two metal plates each having a vertical slit are projected from the main body 1, and inside the main body 1, lead wires (for telephone wires) ) 5 and the lead wire 5 is pulled out upward from the upper part of the main body 1.

The cap 6 which covers the terminals 3 and 3 is made of synthetic resin, and the four caps 6 are screwed onto the main body 1. A through hole for inserting the screw 4 is bored in the center of the cap 6, and a nut 7 is rotatably fitted and inserted in the hole, and the cap 6 is attached so as to cover the terminals 3 and 3. 7 is screwed into the screw 4, and the cap 6 is clamped and fixed on the main body by the rotation of the nut 7. Further, the cap 6 has holes 6 that reach the terminals 3 and 3 in the lateral direction.
a is provided, and a telephone line for connection is inserted through this hole 6a.

On the other hand, below the two caps 6, that is, between the main body 1,
The communication terminal 10 is clamped and fixed. This contact terminal 10
As shown in FIGS. 4 and 5, a metal plate 11 having a mounting hole 12 in the center and an insulating plate 16 attached on the center of the metal plate 11 are provided, and a connecting portion 11a is formed at the tip of the metal plate 11. Is
Two lead wires 14 are soldered to the ends. Metal plate 1
An annular insulator 15 is provided around the first mounting hole 12, and an insulating plate 16 having a hole is attached to the center of the metal plate 11. The connecting portion 11a is made of a soft synthetic resin protective cap 17 filled with silicon grease.
However, it can be detachably covered for rust prevention.

The connecting terminal 10 configured as described above is mounted by inserting the mounting hole 12 into the screw 4 on the main body 1 with the cap 6 removed. Then, the cap 6 is mounted so that the nut 7 is screwed onto the screw 4 so as to cover the terminal 3, and the nut 7 is rotated to fix the cap 6 on the main body. In this state, the connecting terminal 10 is securely sandwiched and fixed between the main body 1 and the cap 6. Two connecting terminals 10 are mounted on the above terminal block.

In this way, the connecting terminal 10 is fitted and inserted into the screw 4, and is sandwiched between the cap 6 and the main body 1 to be attached, so that the connecting terminal 10 can be easily and surely attached to a ready-made terminal block.

The terminal block with the connecting terminal 10 attached is
The lead wire 5 for the telephone wire is attached to the telephone wire cable, and the lead wire 14 for the contact wire is connected to the contact wire. Then, the line from the subscriber telephone is inserted into the slit of the terminal 3 through the hole 6a of the cap 6 and is connected by tightening the cap 6.

When constructing the telephone line, the worker removes the protective cap 17 of the connecting portion 11a of the communication terminal 10 and inserts the connecting wire of the breast into the connecting portion 11a with a clip or the like to connect. Then, the worker tests and confirms the connection state of the telephone line while communicating with the test stand of the station via the communication line.

<Effects of the Invention> As described above, according to the terminal block for the connection terminal box of the present invention, the insulating cap is arranged on the terminal provided in the connection terminal box of the telephone line cable and protruding from the main body. In the terminal block for the connection terminal box where the cover and the cap are screwed to the main body, the contact terminal is sandwiched and fixed between the cap and the main body. It is not necessary to install the block in the connection terminal box in the limited space. Therefore,
The work time for mounting the dedicated terminal block inside the box can be shortened, the space and weight inside the box can be reduced, and the cost of connecting parts can be reduced.
